STRADDLE-ROW CULTIVATDR.

SEEGIFICATION lforming part of Letters Patent No. 270,251, dated January '9, 1883.

Applicationled July G, 1882.

To all whom it may concern Be it known that I, PATTRICK RooNEY, of Chariton, in the county of Lucas yand State of Iowa, have invented an Improved Straddle- Row Cultivator, of which the following" is a specification. i

My invention consists inv forming and cornbining cultiwator-frames direct withacarriage in such a manner that they will have vertical and also lateral play,and readily adjusted and directed relative to plants in rows by means y form an eye, that adapts the complete frame bly connected with the frames a b c d.

of the drivers feetin stirrups,and also readily raised and lowered by means of a hand-lever within reach of the driver when seated on the rear end of a carriage body and pole formed integral with each other, all as hereinafter fully set forth.

Figure l ofthe accompanying drawings isa side view ot'rny cultivator-frame. Fig. 2 is a sectional view, and Fig. 3 a perspective View, of' my complete machine. J ointly considered, these figures clearly illustrate the construction and operation of my complete invention.

a is the center bar of my cultivator-frame. It has an upward bend, c', at its front end to to bring the shovels ot' the complete straddle! row cultivator in to a V-shapedline. The three bars are combined by means ot' a screw-bolt,

d, and in'tervening stay-blocks in such a manner that they will be spread apart at their rear ends and adj ustably connected in such a manner that they can be readily expanded or contracted relative to each other, as required to suit the varying widths between the rows of corn'and other plants between which the frame and cultivator are to be operated.

ff represent my footLrests or stirrups, flexi- They may be made of round bar-iron by simply bending short pieces into suit-able shape and then linking them to the bolt d, as clearly (No model.)

shown in Fig. 1. In the practical use thereof `the driver, seated on the rear end of the can riage, places his feet in the stirrups, and by the movements of his feet he can then'readily govern theadvancing cultivators relative to the line of advance, and also relative to the plants, obstructions, and depth ot' soil to be stirred.

gis a single straight piece of wood, that serves as a carriagebody, and also as a pole for attaching horses and moving and governing the carriage.

his my carriage-axle, formed complete in one piece by simply bending a straight round bar of iron into form as shown, and as required to produce a bowed axle.

fi i areV eyes formed at the base of the bow, for the purpose of flexibly connecting thefront endsot" the beams of the cultivatonframes a b c therewith. The top and center oi the bow and axle arerigidly connected with the centralV portion of the carriage-body and` pole g by means of clamping-bolts, or in any suitable way.

k is a semicircular yoke, that has its ends hinged to the eyes i of the bowed axle in such a position that it can be readily vibrated under and within the bow of the axle.

l is an elbow-shaped lever, pivoted rear portion of the carriage-body g.v

` m is a rod connecting the short arm of the lever Z with the top and centerwof the yoke It.

n is a rackfixed to the bodyfg in such a position relative to the lever l that a tlange on the edge ot' the lever will readily engage the to the rack asrequired to retain the lever and the yoke stationary at various angles relative to the carriage and ground. l

r r represent hangers7 that are readily4 made `by simply doubling a rod and forming hooks on its ends adapted to engage the bolts d that connect the central portions ot' `the bars a. b c.

s s represents a cross bar or rod xed to the carriage-body g, to extend horizontally in opposite directions to form supports for the hangers r, that are llexibly connectedtherewith and depend therefrom, to serve as a swinging fulcrum upon which the complete frames a b c d are balanced and operated.

t trepresent posts rigidly iixed to the central portions df the frames a. b c fl.

IOO

w w are links or rods that extend'frorn the tops of the posts t to the bow of the yoke k.

By adjusting the lever in the rack n the yoke k is readily raised or lowered, and by means of the posts t and connecting-bars or rods w flexibly connected with the yoke, the rear end of the suspended cultivators t b c d are lifted up or let down, at the pleasure of the operator, to change the inclination ot the cul` tivator teeth or shovels, and thereby govern their depth in the soil.

I am aware that three curved metal plowbeams of diEerent length have been rigidly connected in a gang-plow by means of braces at their rear ends and a cross-piece and coupling device at their front ends; but my manner of forming a V-shaped cultivatorframe of three graduated bars and adapting 1. In a cnltivator-fralne, a drag bar or beam having an upward bend or loop, in combination with one or more beams having straight front ends, substantially asshown and described, for the purposes specified.

2. The cultivatortrames composed of the drag-hara, having at its front end a bend, a, the adjustably-connected bars `I) c, and the cross-rod d, in combination with the arched axle h, having honest, substantially as shown and described.

3. The carriage-frame g h, the yoke lr, thc lever l, the connecting-rods m, the hangers r s, and the suspended cultivators having posts t, arranged and combined substantially as shown and described,'to operate in the inanner setforth, for the purposes specified.
